The main theme of the following work is an urban regeneration project for a block in the historic center of Castelfranco Emilia, in collaboration with the municipal administration of the city. The block in question is located at the extreme west of Via Emilia, on the edge of the historic center, and currently contains: the Teatro Dadà, a historic city theater, a series of historical aggregates located in Via della Vacca, a residential tower building, and a series of reinforced concrete buildings extremely different in construction materials and geometries compared to the existences of the historic center. The block in question is in an evident state of decay and neglect, which is why the collaboration with the municipal administration and the work contained in this thesis is born.
